The father
of Queen Guenevere, Sir Leodegrance is not only a Knight
of the Round table, but the man who built the Round Table for King
Arthur. This he gave freely to the King upon his proposal to
Guenevere. He also gave Arthur one hundred of his most noble knights
to form the Knights of the Round.

Notes:
Leo summons guardian paladins that group with him and fortify during the fight,
it's best to have some chars with area attacks in a separate group to take them
out and for these chars to be evil so that they don't zap - evil mages or augurers are best. He is immune to slashing and piercing weapons, quantum spike and grasp, but most
stuff works on the paladins just fine. You'll need to realign during fights
if you're not evil.
